There are so many levels to this.
1- knock knock ginger is cruel to the initial victims who are the householders. Old people, parents with babies, anxious people, people grieving, people sleeping, night shift workers, people just going about their business and not wanting to be the sport of others- it’s a game that gives no thought or care to community or people or neighbors. Selfish twat game in other words. (Usually played by children without the faculty to consider the wider social issues)
2- Grown adults “playing” it with the added “benefit” of terrifying children and or taking delight in the involuntary expletives of a disabled child?! Dear lord that takes some brass neck don’t it?
3- those adults are in loco parentis, supposedly “love” these children who (in addition to their unwilling neighbors) they have decided to make sport of for their amusement? Coupled with the doubling down of this right to laugh at , and not with, children, minors, their family /siblings (!) and refusal to accept any accountability for their actions? Adults, even when they thought they were right in the moment, acknowledge the harms they may have unintentionally caused, and apologise accordingly. They don’t make sport of children and the disabled unless they really are shit imo.
4- the recording of their sport for the enjoyment of public consumption of said video presumably for likes and shares, without the consent (and in open disregard of parental consent) of the minors or the neighbors who play victim in these adults “games”? How can they, the whole lot of them, defend this catalogue of actions?
op YANBU and I am so sorry for you. It must hurt so deeply to be so let down, so misunderstood in your position and having so misunderstood who you thought they were, what a devastating series of events for you. Hold your children tightly and take time to come to terms with the implications of all that has unfolded here.
